Hello Tom,
I am not sure if you can help with this but I am at my wits end.
If you hit this site and do a force refresh (ctrl + F5) the site will time
out
and lose connections.
Do the same on port 443 and it does not time out???
The web site I am reffering to is www.tituswill.com

IPSec tunnel mode, through a IPIP tunnel
Hello Gurus,
I am a small problem with routing and here are the details.
Interfaces on my server:
* ipsec0 - 172.19.58.94
* tunl0 - 172.19.58.94
* eth0 - 172.19.58.94
Now, the problem is that there is another host 172.19.58.200. All
communication to 172.19.58.200 should be through tunl0, and all the data
should be secured using IPSec (tunnel mode - because there are more

ipsec tunnel to netgear fvs318
Hi,
I''m trying to set-up an ipsec tunnel between a Redhat9 box and a Netgear

Shorewall (Openswan) IPSEC VPN MASQ Problem

Hello,
You may recall some of My Dmz question around Thanksgiving.
While I have configured a Proxy arp Dmz. I would like to practice
with the routed setup you suggested Tom as your network was
simular.
Here is one of your quotes "The configuration of eth2 is largely
irrelevant but you certainly don''t
